The 7 in 701,280 is in the hundred thousands place.
Answer:
The minimum cost per unit is obtained for an order of 8 units.
Step-by-step explanation:
Since the total cost is modeled by;
C(x)=5x²+320
Then;
1 unit costs; C(x)=5(1)²+320 = 325
cost per unit 325/1 = 325
8 units costs; C(x)=5(8)²+320 = 640
cost per unit = 640/8 = 80
80 units costs; C(x)=5(80)²+320 = 32320
Cost per unit = 32320/80 = 404
The minimum cost per unit is obtained for an order of 8 units.
The answer is 28.26 because to find the area of a circle you need to do pie time radius squared.
-6x + 2y = 8
isolate the y
first add 6x to both sides
2y = 6x + 8
then divide everything by 2 to isolate the y
y = 3x + 4

Total amount of money paid
=11 x 15
=$165
total amount of money sold
=25 x 15
=$375
difference
= 375 - 165
=$210
